@ciaranob updated readings for you...

Current SoH - 89.28%
Current Mileage - 17,102
0 new DCFC sessions since last update
2 charges to 100% since last update
50-75% is my typical SoC at any given time
Great stuff - behind on last three additions but will get it done today.

Will also redraft the second chart so that contributors can better see their data trends and compare to others.

If my battery dies before 8 years and 160k km's it doesn't bother me.
There’s a RWD 2020, with 160k km (info from last November) with SoH 86%.
According to my dealer, owner is/was charging it on DC only.

Yes I loaded that car after you shared previously - I’ll be sure to x-check later today.

As far as i remember, you added before.
I just wanted to comment @andb wish related to SoH at 160k km.

so it’s been a couple of months so here’s an update.


1. unknown
2. 88.39
3. 15,316 Miles
4. Aprox. 80kwh since delivery in 06/23.
5. Build 12/21 initial delivery 2/22

I don’t love to see the SoH dropping more than 2 percentage points. I may try a 100% charge to see what effect that has. I’ve kept the car at 85% charge with the only exception being a dealer visit where they charged it to 100 via dc fast charging.

the other factor is temperature. I live in a warm part of the us. The summer has been miserably hot.
Six months has come and gone! ….here’s an update.


1. unknown
2. 88.39
3. 20,720 Miles
4. Aprox. 180kwh since delivery in 06/23.
5. Build 12/21 initial delivery 2/22

the big takeaway here for me is the SoH is reporting exactly the same as my September update.

The dash currently shows 100% battery. The SoC reported in car scanner is slightly lower. So the is 100% for my battery. Notice the Battery Energy field at the bottom. 76.65 kwh. Now if I multiply the known usable portion of my battery from the factory (83.7) by my SoH (88.39) I get 74 kWh. I’m wonder if the buffer is in play here? Can anyone give me a. Refresher on how the buffer is allocated or utilized?

Despite Porsche stating a net battery capacity of 83.7 kWh it seems the true usable capacity is 86.7 kWh. At a SoH of 88.39% it works out to exactly the 76.6% battery energy shown on Car Scanner.

Is this 86.7 number published anywhere? Thanks for the info! I love it when numbers make sense. Makes me even more curious about the buffer though.

I'm not sure it is actually official/published anywhere but if you go back to the start of this (long) thread you will find multiple references to 86.7 kWh being the real net capacity. As in your case the numbers work if that is the actual net capacity and they don't at 83.7 kWh.
